[0023] Working principle: in the process of pipe piece grabbing, first use the lifting tool to lift the lifting hook 1, place it directly above the pipe piece, the lifting connection mechanism 2 will fall under the action of gravity, the clamp jaw mechanism 4 will move outward along the long slot hole of the rack 28 of the lifting connection mechanism 2 under the action of the lifting connection mechanism 2, the guide roller 48 of the clamp jaw mechanism 4 on both sides will fall along the pipe piece wall, until the clamp jaw mechanism 4 completely falls, then the lifting tool slowly lifts, the lifting connection mechanism 2 rises at the same time, the clamp jaw mechanism 4 is tightened inward under the action of the long slot hole of the rack 28 of the lifting connection mechanism 2, and the pipe piece is grabbed, after the pipe piece is moved to the specified position, the pipe piece is placed down, the clamp is moved, the clamp jaw mechanism 4 will move outward again along the long slot hole of the rack 28 of the lifting connection mechanism 2, and the pipe piece is released, finally the lifting tool is lifted to grab the next pipe piece, and the pipe piece moving process is completed.

[0024] The clamp is in a locked state before moving, and the clamp is moved to the position where the segment is needed to be moved. The clamp is above the segment, and the guide rollers 48 contact the upper side of the segment first. At this time, the clamp is in a locked state, and the safety pin 26 needs to be pulled out and inserted into the placement hole of the placement plate 25. The equipment is unlocked, and the lifting connection mechanism 2 falls under the action of gravity. The clamping jaw mechanisms 4 on both sides have contacted the segment, and the falling is stopped. At this time, the up-and-down moving rollers 42 start to move upwards along the contour of the long groove hole of the steel plate 24 on both sides of the lifting connection mechanism 2 from the lowermost side of the long groove hole. The horizontal moving rollers 43 move outward with the assistance of the H-shaped steel rail 33 to the clamping jaw mechanisms 4, and the clamping jaw mechanisms 4 start to open. The guide rollers 48 move from the upper side of the segment to the two side walls of the segment. When the distance between the guide rollers 48 is greater than the width of the segment, the clamp starts to fall downward. The clamping jaw mechanisms 4 fall downward under the action of gravity, but the up-and-down moving rollers 42 are limited by the long groove hole of the steel plate 24 on both sides of the lifting connection mechanism 2 and are tightened inward. Therefore, the entire clamp is in a balanced state. The clamping jaw mechanisms 4 are limited by the segment, and the segment limits the clamping jaw bodies 49 from being tightened inward. Therefore, the entire clamp rolls downward along the two sides of the segment through the guide rollers 48 on the side walls of the segment. When the guide rollers 48 roll to the lowermost side of the segment and contact the ground, the lifting device stops falling. During the entire falling process of the clamp, the position of the moving rod 210 also moves. Then, the lifting device is lifted. Since the segment is an arc, the middle of the guide rollers 48 is located at the convex position of the segment and is not supported by the segment. The up-and-down moving rollers 42 move downward along the long groove hole of the steel plate 24 on both sides of the lifting connection mechanism 2. The guide rollers 48 start to move inward, and the clamping jaw bodies 49 tighten the segment. At the same time, the position of the moving rod 210 also moves, and the clamping jaw mechanisms 4 are locked. The clamping jaw mechanisms 4 cannot move again, which ensures that the segment will not move accidentally in the air due to the loosening of the clamping jaw mechanisms 4. Then, the segment can be moved to the desired position through the lifting device.

[0025] The pipe segment is moved to the required position, the lifting device is lowered until the pipe segment falls to the ground, at this time the guide roller 48 also falls to the ground, then the lifting device continues to be lowered, the lifting connection mechanism 2 falls under the action of gravity, the clamping jaw mechanisms 4 on both sides have contacted the ground and stop falling, at this time the up-and-down moving rollers 42 start to move upwards from the lowermost part of the long slot hole of the steel plate 24 on both sides of the lifting connection mechanism 2 along the contour of the long slot hole, the horizontal moving rollers 43 move outward with the assistance of the H-shaped steel rail 33 and the clamping jaw mechanisms 4, the clamping jaw mechanisms 4 start to open, the lifting connection mechanism 2 starts to fall under the action of gravity, when the center holes of the steel plates 24 on both sides of the frame 28 of the lifting connection mechanism 2 are at the same height as the round holes of the locking plate 35 in the equipment body 3, the lifting device stops falling, the worker removes the safety pin 26 and inserts it into the center holes of the steel plates 24 on both sides of the frame 28 of the lifting connection mechanism 2 and the round holes of the locking plate 35, the equipment is locked, at the same time the position of the moving rod is also moved, at this time the distance between the clamping jaw mechanisms 4 is greater than the width of the pipe segment, the lifting device can be used to lift the clamp to take the next pipe segment, the above operation can be repeated. If all the pipe segments are moved, the clamp in this state can be stored in the designated place.

[0026] The above merely describes the preferred embodiments of the present application and is not used to limit the present application, any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
